There is no rule that says temperature recorded at exactly noon for instance is the official temperature for the entire day. Temperatures tend to rise throughout the day and then drop at night. Consquently, there is an average for the day that best represents the temperature for that day.  If you look at our report online it will tell you the average daily temperature for the entire range you selected, which is not what you want. However if you download the raw data you'll see what the temps were for specific days.
